I cannot login to my account while I can login to my niece account every single time, on the same PC at almost the same moment.
Here is what I do:
1. Login to my account -> Failed
2. Login to my niece account -> Successful
3. Repeat step 1 and 2 for 10 times, got the same result.

Then I just try live chat with Square Enix Support Center, they keep let me check my router, my internet connection, and my ISP. But he cannot explain why I can login to my niece account without any problem at all.
Then i ask them to try login to my account and see if they can do that. They just end the conversation. Which mean they could not help.
Now what should I do.
Okay so this only happens exactly when you both play right? Otherwise if just one of you is on at a time it works fine correct?
